IMPORTANT NOTE TO THE INSTALLER Read these instructions before commencing installation. Unvented cylinders are a controlled service as defined in the latest edition of the building regulations and should only be fitted by a competent person. The relevant regulations are: England and Wales – Building Regulation G3, Scotland – Technical Standard P3, N Ireland – Building Regulation Part F After installation the commissioning record must be completed and left, with these instructions, with the householder for future reference.

EHC NEPTUNE UNVENTED HOT WATER CYLINDERS

STORAGE PRIOR TO INSTALLATION The EHC Neptune should be stored in its original packaging in an upright position in an area free from excessive damp. Regulations G3+L. HANDLING PRODUCT The EHC Neptune should be carried upright where possible. Assessments of risks for carrying the cylinder should be conducted. Use more than 1 person for carrying where appropriate. Always follow latest guidelines for lifting techniques, to avoid injury and damage to the product. WATER SUPPLY The EHC Neptune operates at 3 bar (controlled by the inlet control set) and is capable of delivering over 50 litres per minute. The high quality inlet control set has been designed to make the most of the flow rates available, however the performance of any unvented system is only as good as the mains water supply. The maximum possible water demand should be assessed, taking into consideration that both hot and cold services are supplied simultaneously from the mains. The water supply should be checked to ensure it can meet these requirements. If necessary, consult the local water company regarding the likely pressure and flow rate availability. If measuring the water pressure, note that a high static (no flow) mains pressure is no guarantee of good flow availability. In a domestic installation 1.5 bar and 25 l/min. should be regarded as the minimum. The maximum mains pressure that the inlet control set can accept is 12 bar. Consideration should be given to upgrading existing ½” (15mm) cold mains pipework to a larger size if the recommended minimum pressure/flow rate is not being achieved. ELECTRIC SUPPLY The EHC Neptune requires 240 Volt electrical supply for the immersion elements. The electrical supply to each immersion heater must be fused at 13A via a double pole isolating switch to BS 3456. The cable must be at least 2.5mm2 heat resistant (85°C HOFR) sheathed flex complying to BS 6141:1981 Table 8.

EHC NEPTUNE UNVENTED HOT WATER CYLINDERS

SITING THE UNIT The EHC Neptune can supply outlets above it or at some distance from it. Site the unit to minimise “dead leg” distances, especially to the point of most frequent use.

Access for maintenance of the valves should be considered. Consideration should be given to position of discharge pipes (tundish), drain valves - shall be positioned away from electrical components.

Outlets above the EHC Neptune will reduce the outlet pressure available by 0.1 bar for every 1m of height difference. The unit should be protected from frost. Particular care is needed if sitting in a garage or outbuilding. All exposed pipework should be insulated. EHC Neptune must be installed VERTICALLY on a flat base capable of supporting the weight of the cylinder when full. See technical specification section (page 16) for weights. The minimum recommended cupboard size is 650mm square.

The immersion heaters are 375mm long and care should be taken to ensure that they can be withdrawn for servicing if required. The discharge pipework from the safety valves should fall continuously and terminate safely.

SCHEMATIC DIAGRAM NOTES: The pressure reducing valve, non-return valve and expansion relief valve are combined together in the inlet control set.

GENERAL INSTALLATION COLD MAINS PIPEWORK Run the cold main through the building to the place where the EHC Neptune is to be installed. Take care not to run the cold pipe near hot water or heating pipework so that the heat pick-up is minimized. Identify the cold water supply pipe and fit an isolating valve (not supplied). A 22mm BS1010 stopcock can typically be used but a 22mm quarter turn full bore valve would be better as it does not restrict the flow as much. Do not use â&#x20AC;&#x153;screwdriver slotâ&#x20AC;? or similar valves. Make the connection to the cold feed of the cylinder and incorporate a drain valve. Position the drain valve no higher than the cold inlet to ensure sufficient draining of cylinder when required. Position the inlet control just ABOVE the Temperature & Pressure Relief Valve (TPRV) mounted on the side of the cylinder. This ensures that the cylinder does not have to be drained down in order to service the inlet control set. Ensure that the arrow points in the direction of the water flow. Select a suitable position for the expansion vessel. Mount it to the wall using the bracket attached to the vessel. Use suitable fittings capable of supporting full vessel weight (and with appropriate consideration to wall material). Connect the expansion vessel to the cold feed pipework between the inlet control set and the cold inlet on the cylinder. Ensure that the top of the vessel is accessible for servicing. CONNECTING TO THE CYLINDER All of the pipework connections on the cylinder are 22mm compression and supplied complete with gland nuts and olives, in the Accessory Kit box. Only connect 22mm Table X copper tube to these connections. Cut the tube with a pipe cutter and ensure no sharp edges or burrs protrude. Slide both gland nut and olive onto the tube and push tube fully home into the connection, ensuring the tube end fully bottoms on the connection recess. Smear the outer wall of the olive with plumbing paste and tighten gland nut in the prescribed manner. Upon filling/commissioning, ensure all connections are completely watertight. Note: No control or isolation valve should be fitted between the expansion relief valve and the storage cylinder. The relief valve connections should not be used for any other purpose.

BALANCED COLD CONNECTION If there are to be showers, bidets or monobloc taps in the installation then a balanced cold supply is necessary. There is a 22mm balanced connection on the inlet set. HOT WATER PIPEWORK Run the first part of the hot water distribution pipework in 22mm. This can be reduced to 15mm and 10mm as appropriate for the type of tap etc. Your aim should be to reduce the volume of the hot draw-off pipework to a practical minimum so that the time taken for the hot water is as quick as possible. Where monobloc mixing taps and showers are used, these should be installed to comply with the Water Supply (Water Fittings) Regulations 1999. If these devices are supplied with un-balanced supplies there should be single check valves installed at both inlets, to stop over pressurising of either supply. PRIMARY COIL CONNECTIONS FOR INDIRECT UNITS For Solar input models refer to pages 11-12 before making any connections. Connect the primary connections (Indirect only) using the compression connections provided. The primary circuit must be positively pumped. Gravity circulation is not suitable. Either primary connection may be used as the primary flow, reheat times are not effected. The primary circuit can be open vented or sealed, with up to a maximum pressure of 3.5 bar. If you seal the primary circuit an additional expansion vessel and safety valve is required. The boiler may be Gas, Electric or Oil but must be under effective thermostatic control. Uncontrolled heat sources such as some AGA’s, back boilers, solid fuel stoves, etc. are NOT SUITABLE. Please contact our Technical department for guidance. Connect the two port zone valve ( indirect only ) into the primary flow pipework. The direction of flow arrow should be towards the primary flow connection.

SECONDARY CIRCULATION The EHC Neptune can be used with secondary circulation. An appropriate WRAS approved bronze circulator should be used in conjunction with a non-return valve to prevent backflow. On large secondary circulation systems it may be necessary to incorporate an extra expansion vessel into the circuit to accommodate the increased system water volume. Secondary circulation should be avoided on Direct electrically heated units being used on off-peak electricity tariffs. A secondary return boss is fitted as standard on 210, 250 & 300 ltr units. On smaller sizes, tee into the cold feed pipe above the drain. IMMERSION HEATERS Only immersion heaters with a thermal cut-out may be used. To help ensure this, the immersion heaters have a special 1 3/4” thread. They are rated at 3kW at 240V and are of a low noise Incoloy construction. They have both a thermostat and a high limit cutout. Please order the correct replacement via ourselves; fitting nonapproved immersions may affect your guarantee. When fitting, ensure the ‘O’ ring is positioned correctly on the head of the immersion heater and lubricate before fitting. Fit it by hand until almost home then tighten gently as the ‘O’ rings will seal easily. The electrical supply to each immersion heater must be fused at 13A via a double pole isolating switch to BS 3456. The cable must be 2.5mm2 heat resistant (85°C HOFR) sheathed flex complying to BS 6141:1981 Table 8. Do not operate the immersion heater/s until the unit is full of water. Do not operate the immersion heater/s if any sterilisation liquid is in the cylinder as this will cause premature failure. ELECTRICAL CONNECTIONS Complete the wiring – use the appropriate wiring diagrams on page 12- 13.

DISCHARGE ARRANGEMENT Note: The discharge will consist of scalding water and steam. Asphalt, roofing felt and non-metallic rainwater goods may be damaged by such discharges.

Diagram of a typical discharge pipe arrangement (extract from Building Regulation G3)

Position the inlet control group so that the discharge from both safety valves can be joined together via a 15mm end feed Tee (see diagram above). Connect the Tundish and route the discharge pipe. The discharge pipework must be routed in accordance with Part G3 of schedule 1 of the Building Regulations. The information that follows is not exhaustive and if you are in doubt you should seek advice. The two safety valves will only discharge water under fault conditions. When operating normally water will not be discharged. The tundish should be vertical, located in the same space as the unvented hot water storage system and

Note: D2 pipe from tundish is now allowed to be installed in soil stacks within premises. This activity is not recommended as discharge from T&P may continue for long periods of time. It is the installerâ&#x20AC;&#x2122;s responsibility to ensure the discharge pipework can support the discharge for prolonged periods. If used follow guidance on mechanical seal without water trap given in G3 Building Regulations. As discharge can be in excess of 90oC discharge into plastic pipework is also not recommended.

be fitted as close as possible to, and lower than, the safety device, with no more than 600mm of pipe between the valve outlet and the tundish. The tundish should be positioned away from electrical devices. Any Discharge should be visible at the tundish. The tundish should be located such that any discharge is visible. In addition, where discharges from safety devices may not be apparent, e.g. people with impaired vision or mobility, consideration should be given to the installation of a suitable safety device to warn when discharge takes place, e.g. electronically operated.

EHC NEPTUNE UNVENTED HOT WATER CYLINDERS

The discharge pipe (D2) from the tundish should: A) Have a vertical section of pipe at least 300mm long, below the tundish before any elbows or bends in the pipework. B) Be installed with a continuous fall of at least 1 in 200 thereafter. The discharge pipe (D2) from the tundish should be of metal or other material that have been demonstrated to be capable of withstanding temperatures of the water discharged. The discharge pipe (D2) should be at least one pipe size larger than the nominal outlet size of the safety device unless its total equivalent hydraulic resistance exceeds that of a straight pipe 9m long i.e. discharge pipes between 9m and 18m equivalent resistance length should be at least two sizes larger than the nominal outlet size of the safety device, between 18 and 27m at least 3 sizes larger, and so on. Bends must be taken into account in calculating the flow resistance. Refer to diagram 1, Table 1 and the worked example. An alternative approach for sizing discharge pipes would be to follow BS670 ce of services supplying water for domestic use within buildings and their curtilages. The discharge pipe (D2) should terminate in a safe place where there is no risk to persons in the vicinity of the discharge. Examples of acceptable discharge arrangements are: a. To a trapped gully with the end of the pipe below the fixed grating and above the water seal. b. Downward discharges at a low level; i.e. up to 100mm above external surfaces such as car parks, hard standings, grassed areas etc. are acceptable providing that where children play or otherwise come into contact with discharges, a wire cage or similar guard is positioned to prevent contact whilst maintaining visibility. c. Discharges at a high level; e.g. in to metal hopper and metal down pipe with the end of the discharge pipe clearly visible or onto a roof capable of withstanding high temperature discharges of water and 3m from any plastic guttering systems that would collect such discharges. d. Device to warn when discharge takes place.

WORKED EXAMPLE The example below is for G1/2 temperature relief valve with a discharge pipe (D2) having 4 No. elbows and length of 7m from the tundish to the point of discharge. From Table 1: Maximum resistance allowed for a straight length of 22mm copper discharge pipe (D2) from a G1/2 temperature relief valve is: 9.0m. Subtract the resistance for 4 No. 22mm elbows at 0.8m each = 3.2m. Therefore the maximum permitted length equates to: 5.8m. 5.8m is less than the actual length of 7m therefore calculate the next largest size. Maximum resistance allowed for a straight length of 28mm pipe (D2) from a G1/2 temperature relief valve equates to: 14m. As the actual length is 7m, a 28mm (D2) copper pipe will be satisfactory.

HIGH LIMIT CONTROL

LOWER COIL: SOLAR INSTALLATION The flow and return from the solar heat source are to be connected to the indirect coil. Either primary coil connection may be utilised as the flow or return. The solar primary circuit must have its own dedicated circulating pump, thermal and safety controls which must be installed as per the solar manufacturers instructions. The solar control system used must be of the solar differential control type and should be connected to the solar sensor. The solar sensor, supplied as part of the solar controls should be inserts into Pocket B and is held in-situ with the black sensor pocket retaining bung provided. It is necessary to connect the solar pump via the overtemperature high limit cut-out (provided) to ensure the heat input to the solar coil is interrupted if the cylinder overheats. Some method to prevent thermosyphoning must also be employed. Non-return check valves in the primary flow and return pipework would be acceptable. If solar controls do not offer appropriate isolation a 2 port zone valve (not supplied) can be used with the pump and high limit stat as shown to the right. NOTE: If it is intended to fit a cylinder with a solar coil to be used at a later date, the 2 coils should be connected in series to make use of the solar coil, using the dual stat in Pocket D.

UPPER COIL The upper coil is connected to the fossil fuel boiler as per the instructions for the EHC Neptune Indirect single coil model with the dual stat control and high limit thermostat inserted into pocket D (diagram page 11). The wiring requirements are as depicted on page 12-13.

HIGH LIMIT CONTROL

WATER The potable water connection and tundish discharge connection are to be connected in exactly the manner described in Pages 5 to 6 of this manual.

GENERAL When installing this product it is essential the overall installation meets all current legislation including, in particular, the high limit isolation requirements of Building Regulation G3. This document is designed to assist in achieving that aim.

The schematic wiring diagrams below depict an IMIT high limit control stat and the connections are numbered accordingly. Where an alternative is supplied connect as per manufacturerâ&#x20AC;&#x2122;s instructions.

SCHEMATIC WIRING

EHC NEPTUNE UNVENTED HOT WATER CYLINDERS

COMMISSIONING FLUSHING & FILLING Check that the pressure in the expansion vessel is 3 bar (45PSI), i.e. the same as the setting of the pressure reducing valve. The valve is of the car tyre (Schrader) type. Check all the connections for tightness including any factory made connections such as the immersion heater and the temperature and pressure relief valve. Before filling, open the hot tap furthest away from the EHC Neptune to let air out. Open the cold main isolation valve and allow the unit to fill. When water flows from the tap allow it to run for a short while to flush through any dirt, swarf or flux residue. Close the tap and open every other hot tap in turn to purge all remaining air.

as required. Allow unit to heat up, adjust the thermostat so that the heater switches off at 60°C. Record information on Commissioning Record (Page 19).

DIRECT UNITS After filling with water and after sterilisation liquid has been purged, switch on the power to the immersion heaters and allow the unit to start to heat. The immersion heater is supplied preset at 55°C. Turning fully to + sets to approx 65°C. Allow unit to heat up, adjust the thermostat so that the heater switches off at 60°C. Record information on Commissioning Record (Page 19).

SAFETY VALVE CHECKS During heat-up there should have been no sign of water coming from either the expansion relief valve or the temperature/pressure relief valve. Now hold both of these safety valves fully open, allowing as much water as possible to flow through the tundish. Check that your discharge pipework is free from debris and is carrying the water away to waste efficiently. Release the valves and check that they reseat properly. On Completion of commissioning, fill in the Commissioning Record and leave with the house owner.

INDIRECT UNITS Consult the boiler manufacturer’s commissioning instructions and fill the primary circuit. Ensure the lever on the two port valve is set to the filling position. When full, move the lever back. Switch the programmer to Domestic Hot Water (DHW) and allow the unit to start to heat. Adjust the dial of the dual thermostat to between 55°C and 65°C

STORAGE TEMPERATURE The recommended storage temperature for both direct and indirect cylinders is 60-65°C. In hard water areas consideration should be given to reducing this to 50-55°C. In many healthcare applications the guidance on Legionella control and safe water delivery temperatures will require storing the water at 60-65°C, distributing at 50- 55°C and using thermostatic mixing valves to control the final temperature. For details consult the NHS Estates Guidance on safe hot water temperatures.

SERVICING

GENERAL Servicing should only be carried out by competent installers and any spare parts used must be purchased from the Electric Heating Company. NEVER bypass any safety devices or operate the unit without them being fully operational.

DRAINING Isolate from the electrical supply to prevent the immersion heaters burning out. Turn off the boiler. Isolate the unit from the cold mains. Attach a hose to the draining tap ensuring that it reaches to a level below the unit (this will ensure an efficient syphon is set up and the maximum amount of water is drained from the unit). First open the hot tap closest to the unit and then open the draining tap. WARNING: WATER DRAINED OFF MAY BE VERY HOT! IMPORTANT: After draining the cylinder do not close the hot tap until the cylinder has fully cooled, failure to follow this instruction may result in damage to the cylinder and will invalidate the guarantee. ANNUAL MAINTENANCE The EHC Neptune requires an annual service in order to ensure safe working and optimum performance. It is essential that the following checks are performed by a competent

installer on an annual basis. Commonly this is done at the same time as the annual boiler service. 1) Twist the cap of the expansion relief valve on the inlet control set and allow water to flow for 5 seconds. Release and make sure it resets correctly. Repeat with the pressure/ / temperature relief valve. In both cases check that the discharge pipework is carrying the water away adequately. If not, check for blockages etc. and clear. WARNING: THE WATER DISCHARGED MAY BE VERY HOT! 2) Check that any immersion heaters fitted are working correctly and that they are controlling the water at a temperature between 55°C and 65°C. 3) Check the pressure in the expansion vessel is charged to 3 bar. Turn off the water supply to the unit and open a hot tap first. The air valve on expansion vessel is a Schrader (car tyre ) type. Air or CO2 may be used to charge the expansion vessel. 4) Unscrew the head on the inlet control set and clean the mesh filter within. 5) The service history supplied with this unit should be updated at each service. YOUR GUARANTEE MAY BE VOID WITHOUT PROOF OF ANNUAL SERVICING.
